Vehicle exhaust collecting and detecting method

Abstract

The invention relates to a vehicle exhaust collecting and detecting method. The method comprises the following steps that an air pump is arranged on one side of a smoke meter; a moving seat is arranged on one side of the air pump, a mounting table is arranged on the moving seat, and an exhaust pipe is mounted on the mounting table through a mounting device; damping devices are mounted on the mounting table and located on the two sides of the exhaust pipe in the radial direction, and the exhaust pipe is fixed to the mounting table through the damping devices; a height adjusting device drives the mounting table to ascend and descend to a proper height, and meanwhile a moving device drives the mounting table to slide towards the exhaust pipe of a motor vehicle, so that an extraction pipe is inserted into the exhaust pipe; the air pump is started, and the air pump extracts exhaust in the exhaust pipe through the extraction pipe and sends the exhaust into the smoke meter through a gas guide pipe; and the smoke meter detects the exhaust of the motor vehicle, and finally detection data is displayed on a display screen on the side wall of the smoke meter, so that detection is completed. The method has the effect of keeping the extraction pipe stable instead of manual work.

Description

technical field [0001] The present application relates to the field of automobile exhaust detection, in particular to a detection method for automobile exhaust collection. Background technique [0002] With the continuous development of the economy, the automobile industry is increasing day by day, and the pollution caused by automobile exhaust emissions is becoming more and more serious. Due to the management of automobile exhaust emissions, automobile exhaust must meet certain emission standards. Therefore, in vehicle performance testing, automobile exhaust detection is a must. An indispensable test item, in the detection of automobile exhaust, smoke meter is generally used to measure the smoke level in the exhaust gas of automobiles. [0003] In related technologies, during the collection and detection of automobile exhaust, personnel insert the sampling tube of the smoke meter into the exhaust pipe of the automobile for sampling. Since the exhaust pipe of the automobile ...
